'IO ALL WHOM I'I MAY CON CERN:

Beit known that I, JOHN R. RICIIARosox, ct' Newcastle, in the county of Lawrence, and in the State of Pennsylvania, have invented certain new and useful Improvements in IIame--Fasteners; and do hereby declare that the following is a full, clear, and exact description thereof, reference heilig had to the accompanying drawings, andto the lett-ers of reference marked thereon. In the annexed drawings, making part' of lthis specitication- A and B represent-two cast metallic bars, provided each at one end with hooks, which are intended to catch into the eyes in the lower end of the llames. The bar A is provided with a series of openings,l:cix, the metal between ssaid openings being berelled off, as seen, on one side, while a square shoulder is left upon the other side. The bar Bis provided with a slot, D, and with two ears,bctween which is'pivoted a tongue, C. The tongue consists of a short metallic bar, with a rib, a, cast upon it, and also a projection, d, and its end opposite the projection made a little bulky or large, to act as a weight. This tongue is so pivoted between the ears e e that the pivot is furthestfrom its large end, thus throwing up that end with the'lug formed upon it. One side of the lug or projection is bevelled, to correspond with the bevel of the metal between the openings in bar A, and one side'is provided with a square shoulder. When the tongue C has been pivoted between the ears'c e, on bar B, the straight or plain end of har A is inserted between it and the metal above it of bar B, and the lug or projection Z of the tongue takes into one of the openings of bar A, the squareshould'er ofthe tongue catching against the shoulder of the metal between the openings of bar A, thus holding the two bars firmly together. The rib a being alittle outside of the pivot, strikes against the under side of bar A, and assists in keeping the tongue C in its position.

The two parts of the haines may be tightened by simply pressing them together, sothat the bar A will be made to move np one or more notches; and said parts may he separated by pressing up the heavy end of the tongue with the thumb or finger, so as to disengage its lug from the bar A, and then drawing the two parts away from each other. One great advantage of this fastening is the simplicity of construction of its parts, and its ease and certainty of operation. The parts can be east with great ease, and this fact renders the cost very little.

What I claim aslnew, and desire to secure by Letters Patent, is

The bar B, withits groove and opening D, and with its ears e c, between which is pivotcd the tongue C, eonstructed as described, for securing the slotted bar A, in the manner and for the purposespecied.

I In testimony that I claim the foregoing I have hereunto set my handthis 29th day of June, 1867.

JOHN n. RICHARDSON.
